256-bit SPI NVSRAM IC, 1MHz, 8-SOIC Package
Stock Quantity: 0
The X24C44S is a 256-bit Serial Peripheral Interface (SPI) non-volatile static random-access memory (NVSRAM) integrated circuit manufactured by XICOR. This memory device offers a 1 MHz clock frequency and is supplied in an 8-pin Small Outline Integrated Circuit (SOIC) package. It combines SRAM technology with EEPROM backup for data retention during power loss.
This NVSRAM is suitable for applications requiring infrequent data updates coupled with fast access times and non-volatile storage. The SPI interface allows for simple integration with microcontrollers and other digital systems.
